六十年代,湖北省开始推广油—稻—稻三熟制油菜。据1963年统计,全省晚茬油菜(包括一季稻和双季稻茬口)近30万亩,占油菜总面积的15％左右。到七十年代初期,三熟制油菜发展很快,1975年已达100万亩,约占油菜总面积的40％。但由于三熟油菜发展历史短,单位面积产量低,生产上存在的技术问题较多。为适应生产发展的需要,油料所从1974年以来,开展了水田三熟制油菜高产栽培的研究,供试品种“甘油3号”,
Sixties, Hubei Province began to promote oil - rice - rice three cooked rape. According to the statistics of 1963, nearly 30 million mu of late crop rape (including one-season and double-season stubble crop) in the province accounts for about 15% of the total area of rape. By the early seventies, the development of the three-crop rape grew rapidly, reaching 1 million mu in 1975, accounting for about 40% of the total canola area. However, due to the short development history of the three-crop rape and low yield per unit area, there are more technical problems in production. In order to meet the needs of the development of production, since 1974, the research on high-yielding cultivation of rapeseed in paddy field has been carried out. The cultivars “Glycerol No.3”
